Application of chip capacitors in consumer electronicsIssuing Time : 2020-06-11
With the development of technology and the diversified development of electronic products, consumer electronics is a large demand for chip capacitors, accounting for up to 45%. As an important component of electronic products, chip capacitors are widely used in many fields such as computers, network communications, consumer electronics, automotive electronics, new energy, industrial control, aerospace and military industries.
With the high density, high integration and miniaturization of electronic circuits and the improvement of the stability, safety, reliability and longevity of chip capacitors, and with the development of science and technology, people's consumer demand has increased, environmental protection requirements, new The birth of the whole machine has made the application fields of miniaturized and medium-high voltage and large-capacity chip capacitors continue to expand, and the demand is increasing. Therefore, the production of chip capacitors will not only shrink in a long time in the future, but will have stronger vitality and broader development space, and it will surely have a faster growth rate.
SMD capacitor: ordinary type, made of porcelain. Single appearance, single appearance, no silk screen on the surface, no polarity. There are many colors, mainly brown, gray, lilac, etc. There are various sizes (for the main size, see the introduction of the size of SMD components in Attachment 1). The basic unit of ordinary chip capacitors: pF.
SMD tantalum capacitor: material tantalum dielectric. There are silk screens on the surface and polarity. There are many colors, mainly black and yellow. A white silk screen on the surface of the tantalum capacitor is used to indicate the positive electrode of the tantalum capacitor, and the capacitance value and working voltage are marked on the silk screen. Most manufacturers also add some tracking marks on the silk screen. There are various sizes (for the main size, see the introduction of the size of SMD components in Attachment 1). The basic unit of chip tantalum capacitor: μF.
SMD electrolytic capacitor: material electrolyte. There are silk screens on the surface and polarity. The aluminum casing is visible on the exterior. There is a black silk screen on the surface of the electrolytic capacitor to indicate the negative electrode of the electrolytic capacitor, and the capacitance value and working voltage are marked on the silk screen. Most manufacturers also add some tracking marks on the silk screen. There are various sizes (for the main size, see the introduction of the size of SMD components in Attachment 1). The basic unit of SMD electrolytic capacitor: μF
